About vCenter Server5.1 & vCenter Infrastructure Navigator 2.0

HI Everyone,

I have been installed vCenter Infrastructure Navigator 1.0 and synced vCenter 5.0 successful.

But, after I updated vCenter to 5.1 version, I tried  to remove vCenter Infrastructure Navigator 1.0's plug in vcenter/mob,and I installed vCenter Infrastructure Navigator 2.0,it won't appear in vCenter5.1 plug manager

So,I can't use it, I have tried to re-install it so many time,and check so many VMware KBs and community articles,I am still not luck!!!

Please give me some good advises,thanks a lot.

Regards,

Rocky
